Bug Report

We are experiencing timeouts in TiDB and numerous 'deadline exceeded' errors in TiKV. However, we are unable to identify where the requests are getting stuck. It is unclear whether they are stuck in the process of renewing the leader lease, reading the index, or encountering another issue entirely. To effectively debug these issues, we need to enhance observability in this specific area.
